Legend:
X = Don’t care
RA = Read Address of memory location to be read.
RD = Read Data read from location RA during read operation.
PA = Program Address. Addresses latch on falling edge of WE# or CE# pulse, whichever happens later.
PD = Program Data for location PA. Data latches on rising edge of WE# or CE# pulse, whichever happens first.
SA = Sector Address of sector to be verified (in autoselect mode) or erased. Address bits A19–A15 uniquely select any sector.

Notes:

See
Table 1, on page 10
for description of bus operations.
All values are in hexadecimal.
Shaded cells indicate read cycles. All others are write
cycles.
During unlock and command cycles, when lower address
bits are 555 or 2AA as shown in table, address bits above
A11 and data bits above DQ7 are don’t care.
No unlock or command cycles required when device is in
read mode.
Reset command is required to return to read mode (or to
erase-suspend-read mode if previously in Erase Suspend)
when device is in autoselect mode, or if DQ5 goes high
while device is providing status information.
Fourth cycle of the autoselect command sequence is a
read cycle. Data bits DQ15–DQ8 are don’t care. See
“Autoselect Command Sequence” on page 24
for more
information.
Device ID must be read in three cycles.

Data is 00h for an unprotected sector group and 01h for a
protected sector group.
10. Unlock Bypass command is required prior to Unlock
Bypass Program command.
11. Unlock Bypass Reset command is required to return to
read mode when device is in unlock bypass mode.
12. System may read and program in non-erasing sectors, or
enter autoselect mode, when in Erase Suspend mode.
Erase Suspend command is valid only during a sector
erase operation.
13. Erase Resume command is valid only during Erase
Suspend mode.
14. Command is valid when device is ready to read array data
or when device is in autoselect mode.
15. Data is 83h for factory locked and 03h for not factory
locked.
